Comparative ligand mapping from MHC class I positive cells - The present invention relates generally to a methodology for the isolation, purification and identification of peptide ligands presented by MHC positive cells. In particular, the methodology of the present invention relates to the isolation, purification and identification of these peptide ligands from soluble class I and class II MHC molecules which may be from uninfected, infected, or tumorigenic cells. The methodology of the present invention broadly allows for these peptide ligands and their cognate source proteins thereof to be identified and used as markers for infected versus uninfected cells and/or tumorigenic versus nontumorigenic cells, with said identification being useful for marking or targeting a cell for therapeutic treatment or priming the immune response against infected/tumorigenic cells.

Methods for removing anti-MHC antibodies from a sample - The present invention relates generally to anti-MHC assay methodologies utilizing functionally active, recombinantly produced, and truncated individual soluble MHC trimolecular complexes that are linked to a substrate. The methods include reacting a sample with the substrate having the MHC trimolecular complex linked thereto, whereby antibodies specific for the at least one MHC trimolecular complex linked to the substrate are removed from the biological sample.

METHOD AND APPARATUS FOR THE PRODUCTION OF SOLUBLE MHC ANTIGENS AND USES THEREOF - The field of the invention relates in general to at least one method and apparatus for the production of soluble MHC antigens and more particularly, but not by way of limitation, to at least one method and apparatus for the production of soluble Class I and II HLA molecules. The field of the invention also includes such produced soluble Class I and II HLA molecules and their use. According to the methodology of the present invention, the soluble Class I and II HLA molecules can be produced from either gDNA or cDNA starting material.

EPITOPE TESTING USING SOLUBLE HLA - The present invention relates generally to a methodology for assaying the binding of a peptide to an individual, specific, soluble HLA molecule.

SELECTIVE ANTI-HLA ANTIBODY REMOVAL DEVICE AND METHODS OF PRODUCTION AND USE THEREOF - An anti-MHC removal device includes a serologically active, soluble MHC moiety covalently coupled to a solid support. Methods of production include covalently coupling the serologically active, soluble MHC moiety to the solid support. Methods of use of the anti-MHC removal device include contacting a biological sample with the device so that antibodies specific for the MHC moiety are removed from the biological sample. The biological sample is then recovered.
